Solve the following equation for x:

7(x - 9) = -21+21

x =

1 answer

To solve the equation \( 7(x - 9) = -21 + 21 \), we first simplify the right side:

\[ -21 + 21 = 0 \]

Now, the equation is:

\[ 7(x - 9) = 0 \]

Next, we divide both sides by 7:

\[ x - 9 = 0 \]

Now, we add 9 to both sides:

\[ x = 9 \]

Thus, the solution is:

\[ x = 9 \]
